So saw this on the swtor forum earlier and went wtf. Heavy spoiler warning so only click the blackend text if you're ok with spoilers. Same with the video.
Apparantly at the end of act III in the Jedi Knight storyline you defeat the emperor...
I know the character we play are the heroes and all but a lone Jedi Knight kills the emperor... the strongest darkside force user that has stayed in power for over a millenia?
Now in act II you faced the emperor too and lost even with 3 other jedis at your side and apparantly in act III when you kill him he's weakened because you interupted some ritual but cmon... For a Bioware game that's extremely bad writing.
Here's a video: http://www.youtube.com/watch?v=YpnJeYVvhps
